“…To improve computation efficiency, the rigid body is used to model the tool geometry and the symmetric semi-tube modeling method is applied. The details such as physical properties, meshing, etc., involved in the FE modeling of heating and warm bending can be found in [ 6 ]. Here, only the material properties of CP-Ti tubular material are introduced.…”

“…Here, only the material properties of CP-Ti tubular material are introduced. According to [ 6 ], the true stress-strain curves of the uniform deformation stage (before necking) of the CP-Ti tube are at 25~500 °C, as shown in Figure 3 . It could be found from this figure that the CP-Ti present a significant improvement of the elongation and the uniform deformation under 150~300 °C, which could be possibly used as the temperature window for bending process.…”

“…Li et al studied the springback behaviors of the high strength titanium tube under multi-die constrained cold rotary draw bending by using the analytical modeling, the explicit/implicit 3D-FE modeling, and experiments, indicating that the angular springback increases linearly with increasing the bending angle, while the radius growth slightly fluctuates with the increase of bending angle at the latter bending stage [ 16 ]. Zhang et al constructed a finite element (FE) model for heating-bending of a large-diameter pure titanium tube [ 6 ]. From the view of material property, the influences of anisotropy, the Bauschinger effect, and the degradation effect of elastic modulus on springback of tube bending were also studied [ 17 , 18 , 19 , 20 ].…”

Titanium bent tubular parts attract extensive applications, thus meeting the ever-growing demands for light weight, high reliability, and long service life, etc. To improve bending limit and forming quality, local-heat-assisted bending has been developed. However, significant springback seriously reduces the dimensional accuracy of the bent tubular parts even under elevated forming temperatures, and coupled thermal-mechanical working conditions make springback behavior more complex and difficult to control in warm bending of titanium tubular materials. In this paper, using warm bending of thin-walled commercial pure titanium tube as a case, a coupled thermal-mechanical finite element model of through-process heating-bending-unloading is constructed and verified, for predicting the springback behavior in warm bending. Based on the model, the time-dependent evolutions of springback angle and residual stress distribution during thermal-mechanical unloading are studied. In addition, the influences of forming temperature and bending angle on springback angle, thickness variation, and cross-section flattening of bent tubes are clarified. This research provides a fundamental understanding of the thermal-mechanical-affected springback behavior upon local-heat-assisted bending for improving the forming accuracy of titanium bent tubular parts and structures.

The temperature distribution characteristics in high-frequency induction brazing of cubic boron nitride (CBN) super-abrasive grains is investigated based on finite element simulation in this article. Influences of the following factors, i.e., current frequency, current magnitude, heating gap, and scanning speed, on the resultant heating temperature are discussed. The results obtained display that, during the rotating induction heating process, the effective heating zone is concentrated on the top surface of the metallic wheel substrate (i.e., AISI 1045 steel) below the coil. The highest value of the resultant heating temperature becomes larger when heating with a higher current frequency, a higher current magnitude, and smaller heating gap values; however, a higher peripheral scanning speed results in a decrease of the resultant highest temperature. The optimum parameters are determined as the heating gap of 2 mm, current frequency of 1 MHz, current magnitude of 20 A, and peripheral scanning speed of 0.5 mm/s. Finally, the simulation results are testified and validated in the high-frequency induction brazing experiment of CBN grains.
